In a study that cultivated coral 'gardens' with varying numbers of species, plots with more species were healthier. This finding could inform strategies to help coral reefs survive climate change.
Coral reefs contain an intricate web of predators and prey.
Researchers have just discovered a new species of bacteria that cranks out a deadly toxin. In a common arrangement in the marine environment, a slug and alga both use this toxin for their own defense.

There are more satellites than ever before, orbiting Earth and collecting data that's crucial for scientists. Why do some nations choose not to share that data openly?
How do they each know what to do?
Researchers identified simple behavioral rules that allow these tiny creatures to collaboratively build elaborate structures, with no one in charge.
How do they do while sleeping what we can barely do at all?

These birds spend long periods, often asleep, standing on one leg. Is it passive biomechanics or active nervous system control of their muscles that allows them to do easily what's impossible for us?

New parenthood got our fluid dynamics experts thinking about what ends up in the diaper. They headed to the zoo and the lab to come up with a cohesive physics story for how defecation works.
Gotcha, five times faster than the blink of an eye.

How do a frog's tongue and saliva work together to be sticky enough to lift 1.4 times the animal's body weight? Painstaking lab work found their spit switches between two distinct phases to nab prey.
As temperatures rise, will species have enough habitat to move to suitable ground?
Animals and plants will need escape hatches to move to cooler climes as the planet warms, but few parts of the U.S. have the natural habitat available for these migrations.

Hair as helpers in the quest for cleanliness.
Cleanliness is next to godliness. Did you know hairiness is a part of the equation as well?
Before you ask, they probably haven’t seen Twilight.
Real life blood suckers live among us but they don't want you to know about it.

The more we understand about earthquakes, the more we can do to reduce their impact.
The magnitude 9.0 Tōhoku-Oki earthquake of March 11 last year was the largest earthquake in Japan’s modern history. In fact, it was the fourth-largest earthquake anywhere in the world since 1900. The earthquake…
